Referring to the drawings, Ill represents a supporting plate or platformwhich carries the other parts of the accessory and which also supportsthe base of the telephone with which the accessory is to be used. Theplatform is shown as being rectangular in shape but the shape of theplatform may be widely varied. The platform may be formed of anysuitable material such as laminated woodror molded plastic. The platformmay be provided with felt pads l2, l2 in order to avoid scratching ormarring the desk on which the platform may be placed. A stud I3 may beprovided at the front right corner of the platform which may be manuallyengaged for moving the entire platform.

Carried by the platform is a vertical post l4 which serves to supportvarious other parts as hereinafter explained in detail. The post I4 ispreferably detachably connected with the platform It and as shown inFig. 4 the platform is provided with a vertical stud I6 which is held inplace by a screw it. The stud it enters and fits a central verticalopening in the bottom portion of the post. It will be seen that the postcan be readily engaged with or disengaged from the stud. Preferably thestud I6 is provided with a flange 20 and the post I4 is provided with amating flange 22. A pin 24 projects upward from the flange 20 andthrough an aperture in the flange 22. The pin 24 serves to locate thepost in a predetermined position with respect to the stud l5 and withrespect to the platform It.

Supported on the post [4 by various parts to be described in detail is aholder 26 for the combined transmitter and receiver 28 of the telephone.The base 30 of the telephone is supported on the platform It adjacentthe post M. For convenience of illustration the telephone base 30 isshown in Figs. 1, 2 and G as positioned with its edges parallel with theedges of the platform, but in use it is ordinarily more convenient forthe base to be diagonally positioned. Preferably the platform It haslines 32 described thereon for indicating the most convenient locationof the base with respect to the platform and for indicating the properspacing of the base from the post 14. Normally the transmitter andreceiver 28 is supported by the holder 25 so long as the accessory is inplace and it is not returned to engagement with the base 30.

The base 30 has the usual vertically movable button 34 which is held inits lower open-circuit position by the combined transmitter and receiverwhen the latter is in its originally intended position on the base, thesaid button being biased to its upper closed-circuit position. However,when the present accessory is in place the transmitter and receiver issupportedon the holder I the post l4 and this mechanism will now bedescribed.

Vertically movable on the post I4 is a slide which is preferably in theform of a sleeve surrounding and fitting the post. Carried by thr [side]slide or sleeve 35 is a horizontally extending arm 38 which extends overthe button 34 as shown in Figs. 1, 2 and 6, Preferably the sleeve 36 isguided for vertical movement on the post l4, relative rotative movementbeing prevented. As shown, the sleeve 35 is provided with a verticalinterior spline 4t and the post carries a pin 42 which enters the saidspline. Thus the sleeve 36 is free for vertical movement, but relativerotative movement is prevented.

Preferably the arm 38 is rotatively connected with the sleeve 36, thisbeing desirable in order that the telephone base may be placed indifferent positions on the platform [0. As shown, the main portion ofthe arm 38 is formed integrally with a centrally ap'ertured hub 44. Aportion of the aperture in the hub fits the post 14 and another portionfits a reduced portion of the sleeve 36.

For vertically moving the sleeve 36 and the arm 33 there is provided atleast one manually movable eccentric and preferably there are two sucheccentrics. As shown, the post [4 is flattened at opposite sides and arotatable shaft 46 extends through a horizontal bearing aperture in thepost. Secured to the shaft 46 are two similar eccentrics 43, @8 whichengage the opposite flat faces of the post. Connected with the shaft 46and the eccentrics 48, i8 is a manually operable lever 50 for Ill)turningthe said shaft and eccentrics. When the lever 50 is in the upperposition, as shown in Figs. 1, 6 and 7 the eccentrics are in thepositions to permit the sleeve 36 and the arm 38 to move to theirlowermost positions. is moved to its lowermost position, as shown inFig. 2, the eccentrics are moved to the positions shown in Fig. '2 andthe sleeve 36 and the arm 38 are moved to their uppermost positions.Inasmuch as there are twoeccentric's, pressure is applied to the sleeve36 at both sides of the post. A pin 52 on the post 14 limits themovement of the lever 50, so that thesleeve 36 and the arm 38 are eitherin their lowermost positions or in their uppermost positions. Preferablythe lever 50 has notches asshown to receive the pin 52.

Aspring is preferably provided for biasing the sleeve 38 and the arm 38in the downward direction and as shown there is a coil spring *54 whichsurrounds the upper portion of the post l4 and which is within an upwardextension of the hub- 44 on the arm 38. The upper end of the spring 54abuts against a nut 55 having threaded engagement with the upper end ofthe post I4.

As has been stated, the arm 38 engages the button 34 on the'base of thetelephone. When the 'lever 50 is moved to the position shown in Figs. 1,Band -7, the-arm '38 is moved downward by gravity and by the spring 54'so as to depress the button 34 to its lower open-circuit position. Whenthe lever"'50is moved"to the position shown in Fig. 2, the sleeve '36and the arm 38 are moved upward thus permitting the button 34 to assumeWhen the lever 55 4 its upper closed-circuit position. Thus the user ofthe accessory can close or open the telephone circuit at will by merelymoving the lever 53.

The base of the telephone has the usual upward projections 58, 58 atopposite sides of the button 34 and preferably the arm 38 is providedwith a pair of aligned rollers positioned respectively for engagementwith the said projections 58, 58 atthe sides thereof adjacent the post14. As shown, there are two pairs of rollers which are so positionedthat the rollers of the said pairs are at opposite sides of the saidprojections 58, 58. The rollers of one pair are indicated at 60, 80 andthe rollers of the other pair are indicated at 62, 62, the rollers 65,60 being at opposite sides of the front projection 58 and the rollers62, 62 being at opposite sides of the rear projection 58. The rollersare preferably formed at least in part of rubber or equivalent material.

Preferably each two rollers 60 and 62 are retatably mounted on a pin 64as shown in Figs. 7 and 8, the rollers being held in place by means ofscrews 65, B6. The main body of the arm 38 is provided with transverserecesses 58, 6B.

The arm 38 includes a separate bottom plate 10 which is held in place byscrews and which closes the bottoms of the recesses 68, 68. Verticalpivot pins 12 extend through thepins 64, B4 and through the main body ofthe arm 38 and through the bottom plate 10 thereof. Thus the pins 64, 64which carry the rollers are free for slight :oscillatory movement.

The telephone base 30 is accurately positioned on the platform 10 sothat the projections 58, 55 thereof are between the pairs of rollers 50,60 and 62, '62. The rollers constitute anti-friction means which permitthe arm 38 to vmove freely upward or downward with respect to the baseand inasmuch as the said rollers are formed at least in part of rubberor equivalent material, there is no possibility of scratching or marringthe said projections on the base. Inasmuch as the rollers can oscillatethey can adjust themselves to minor inaccuracies in the location ofthebase 35 with respect to the post I'4.

The telephone base shown in Fig. l is that of a standard telephone.Certain other telephones, as for instance those for inter-office use,have the button 34 at a slightly higher elevation. To accommodate suchhigher elevation of the button 34 an alternative stud 74 may beprovided, as shown in Fig. 5, this stud being provided with a flange '76which is somewhat thicker than the flange 26 shown in Figs. 1, 4, 6 and'7. The flange 16 of greater thickness :holds the entire accessory at 'aslightly higher elevation so as to accommodate the higher :elevation ofthe button 34 The upper portion of the post 14 hasa central cylindricalaperture therein and a vertical rod 18 accurately fits this aperture,being rotatable therein. The lower'end'of the rod 78 is preferablyreduced in "diameter, and the lower end of the aper'ture in the post F4'has'a corresponding reduced diameter. There is thus provided a"shoulder 15 which con'stitutesa bearing for supporting the red when it'is in its lowermost position as shown.

A laterally extending arm 88 '"is provided which is connected at one endwith the upper end of the rod 18. The arm 88 is pivotally movablerelatively to the rod -'to positions at vertically different angles. Asshown a two-part socket clamp is connected with the upper end of the rodI8, this clamp having left and right parts 80 and 82 formed of sheetmetal. The left part 80 of the clamp has an offset 84 to which issecured a nut86. As clearly shown in Fig. 7, the upper end of the rod 18is reduced in diameter and is threaded for engagement with the nut 86.The extreme upper end portion of the rod I8 is peened or riveted to holdthe rod 18 and the nut 86 in permanent engagement.

The laterally extending arm 88 is shown as having a ball-likeenlargement 90 which is clamped between the two parts 80 and 82 of theclamp. The projecting end of the arm 88 carries the holder 26 in amanner to be described. A bolt 92 extends through apertures in the twoparts 80 and 82 of the clamp and is engaged by a nut 94. By turning thenut 94 the bolt acts to draw the two parts 80 and 82 of the clamp towardeach other so as to clamp between them the ball-like enlargement 90 ofthe arm 88.

A member is provided which is carried by the the said rod I8 and whichhas therein a plurality of notches of different depths for receiving thearm 88 and for supporting it in any one of a plurality of positions atvertically difierent angles. As shown, the said ball-like enlargement 90of the arm is generally pear-shaped and the right part 82 of the clampconstitutes the said notched member, and is provided with a plurality ofnotches 96, 66 into which the right end of the ball-like enlargement 90can fit. As shown, there are three notches which are of differentdepths. the ball-like enlargement 90 is seated in one or another of thenotches 66, 90 the arm 88 can be held in three angularly differentpositions. This makes it possible for the holder 26 and the combinedtransmitter and receiver 28 to be held not only in different elevationsbut at different angular positions'to suit the convenience of the user.

Under some circumstances it may be desirable to provide for angularpositions of the arm 88 additional to those which are provided by thethree notches 96, 86. When this is desirable the ball-like enlargement90 of the arm 88 may be provided with annular grooves 68, 98 and theedges of the clamp part 80 may be provided with lips I adapted to beseated in one or another of the grooves 68, 98'by means of the saidgrooves 98 and the said lips I60, the ball-dike enlargement 90 may begripped and held in positions other than the positions attained by theengagement of the said ball-like enlargement with the bottoms of thenotches 96, 68.

The holder 26 is preferably so connected with the arm 88 that it may berotatably adjusted with respect thereto. As shown there is provided adisc I02 having a hollow hub I04 which is interiorly threaded forengagement with a threaded end portion of the arm 88. A second disc I06is provided which normally has face to face engagement with the discI02. The before-mentioned holder includes a sheet metal plate I08 andthis plate is connected by means of rivets IIO with a flange II2 formedintegrally with the disc I06. The disc I06 is provided with an. integralstud II4 which extends through an aperture in the disc I02 and into thehollow hub I04 thereof. A coil compression spring H6 is located withinthe hub I04 and surrounds the stud I I4. A screw I I8 has threadedengagement with By placing the arm 88 so that p the stud H4 and the headof the screw serves as an abutment-for the spring H6. It will be seenthat the spring II6 normally holds the disc I06 in engagement with thedisc I02, but permits it 6 to be slightly separated therefrom whendesired. After the parts have been assembled as shown in Fig. 12 a pinI20 may be inserted through the hub I04 and through the threaded end ofthe arm '88 to permanently lock the parts in assembled relationship.

The discs I02 and I 06 are provided with means which enables them'tointerengage with each other so that the disc I06 may be releasably heldin a variety of positions of rotative adjustment with respect to thedisc I02. As shown in Fig. 13, the disc I02 has an annular series ofholes I 22, I22 therein and the disc I06 carries a pin I24 adapted toenter any one of the holes I22, I22. It will be seen that the angularposition of the holder 26 with respect to the arm 88 can be changed bymoving the holder toward the right in opposition to the spring I I6,thus. withdrawing the pin I24 from the hole I22 in the disc I02. Thenthe holder can be rotated with respect to the arm 88 and released, thepin I24 entering another hole I22 in the disc I02. Thus the holder isnormally held against relative rotation, but can be angularly adjustedas desired.

The holder 26 includes not only the beforementioned plate I08 but alsotwo clips I26, I26 which are adapted to receive and hold the combinedtransmitter and receiver 28. Clips I26, I26 may be varied as to detailsbut I prefer to provide clips as shown in detail in Fig. 14. As shown,each clip comprises a generally U-shaped metallic spring I28 secured tothe plate I08 by means of a rivet I30. Each clip also includes agenerally U-shaped body I32 of yieldable resilient material such asrubber, the body I32 being within the confines of the spring I28. Theinterior of the U-shaped body I32 is shaped to substantially fit thecorresponding portion of the combined transmitter and receiver. When thetransmitter and receiver is to be put in place on the holder it ispushed toward the plate I08, the clips spreading s'ui'ficiently .topermit the said transmitter and receiver to enter the interior'openingin the base I32 of rubber or equivalent material. Thus the transmitterand receiver is firmly held in place and is engaged only by the bodiesof rubber or equivalent material, thus avoiding any possibility ofscratching or marring the said transmitter and receiver.

As has been stated, the arm 88 may be angularly adjusted vertically,thus changing the height of the holder 26 and of the transmitter andreceiver 28. However, the adjustment of the arm 88 is depended uponprimarily for changing the angle of the transmitter and receiver ratherthan for changin the elevation thereof. The elevation of the transmitterand receiver may be changed by vertically moving the rod 78 with respectto the post I4. The rod I8 has two or more annular grooves I34, I34therein and the rod 78 can be raised to locate any one of the saidgrooves I34, I34 just above the top of the nut 56. Withthe rod I0 soraised, a stop I 36, as shown in detail in Figs. 9 and 10, is engagedwith the said rod at the last said groove thereof. As shown, the stopI36 comprises a lower plate I38 having a notch therein, and the notchedportion of the said plate I38 is adapted to enter the annular groove inthe rod 18, the said plate I38 resting on the nut 56 as shown in Fig. 9.The stop I36 also includes a spring I40 which embraces the rod 18 and isshaped to engage the rod to resiliently hold the stop in place. The stomay also comprise a second plate I42 at the top for covering the springI40.

Fig. 7 shows the rod I8 in its lowermost position, it bein supported onthe shoulder at I9. The rod can be raised to position either of thegrooves I34, Iii-l adjacent the top of the nut 55', and the stop I36 canbe snapped in place. Fig. 2

shows the rod 78 raised and'shows the stop I36 engaged with the rod atthe lower groove 34 therein. The rod I8 can be held at any one of threeelevations, and the number of positions may be increased by increasingthe number of annular grooves I34, I34.

Preferably the rod I8 is provided with an additional annular groove nearthe top thereof with which the stop I35 can be engaged when the rod isin its lowermost position as shown in Fig. 7. When the stop is in theposition shown in Fig. 7 it has no function, but it is retained in placeso that it will not be lost.

The usual cord I44, connecting the transmitter and receiver with thebase, may be held by a hook I46 carried by the arm 88. Thus the cord ismaintained in a convenient elevated position.

From the foregoing description it will be apparent that the transmitterand receiver 28 may be held in any position that is most convenient forthe user. It may be adjusted angularly in one direction by changin theposition of the arm 88 with respect to the socket clamp and it may beangularly adjusted in another direction by changing the positionof thedisc I 05 with respect to the disc N32. The elevation may be changed byraising the rod I8 and putting the stop I in place at one of the groovesI34, I34. The transmitter and receiver can at all times be freelyrotated about the axis of the rod I8 and the post I4;

With the transmitter and receiver adjusted to the most convenientposition, the user has his hands free at all times for handling papersand for making notes and the like. When the telephone is not in use thelever 58 is in its upper position as shown in Fig. 1. Whenever thetelephone is to be used the user merely moves the lever 5% to its lowerposition as shown in Fig. 2,

thus opening the telephone circuit so that the desired number can bedialed in the usual manner. Upon completion of use the lever 53 isrestored to the position shown in Fig. 1.
